BURG-LAR ALARM.

Application filed January 6, 1923.

To all whom t may concern.' i,

Beitl known that I. Srnvn Fonon, a citizen of Hungary, residing atOrient, in the county ot' Franklin and State of Illinois, have inventedcertain new and useful lmprovements in Burglar Alarms, of which thefollowing is a specification.

This invention relates to new and useful improvements in burglar alarmsand fun ther provides a protection against such intruders. .l

An important object of Ithe invention is to provide a device suitablefor use as a protection against bank robbers as well as for sounding analarm.

A further object of the invention is to provide a device of the abovementioned character that is controlled by the. bank cashier or tellersfor performing its desired function and wherein the device will beautomatically reset, for repeated use.

A further object is to provide means for actuating a device of the abovecharacter and wherein the control for said. means may be modified tovadapt the device for many uses without materially changing theconstruction of the device or its actuating means.

A further object of the linvention is to provide a device that is simplein construction,'reliable, in operation, strong, and duparts throughoutthe same, 40

rable. l

Other objects and advantages vention Will be apparent during of thefollowing description.

In the accompanying drawing -forming a part of this specification and inwhich like numerals are employed to designate like of the Iinthe courseFigure 1 is a front, elevational view of a portion of the interior of abank and shows teller window with the device associated therewith andindicated in' dotted line,

Figure 2 is a top plan view of the device with the casing iir section tobetter show its contents, and further shows a. source of controllingmeans.

windows 1 formed therein. The device, as

'indicated in dotted lines, is preferably positioned rearwardly of thesaid partition and below the counter portion E2. vThere is furtherprovided a small inconspicuous opening 3 through which the bullts fromthe device are allowed to pass when the apparatus is used as aprotection against bank robbers. i

Referring particularly to Figs. 2 and 3 there is shown the preferredembodiment of the invention and consists of a box or cas-- ing that isadapted to house the device, with the exception of the electric wiringand its may be varied to suit the occasion, and, therefore, does notenter'into the spirit of this invention. tom wall 4, side walls 5, andend walls 6 and 7, while the top of the box is closed by This boxembodies a bot- 'lov 'It is to be understood-.- that the mounting orsupport for this box' as by the bracket member 10 that encircles thebarrel and conforms in shape therewith. This bracket member is providedwith laterally extending arms 11 that are adapted to be secured tov theend wall 6 by the screws 12. Secured to the bottom wall 4 is a block 13that is provided with a pocket 14 that conforms in shape with the lowerend of the hand grip 15 and is adapted to rigidly support 'thesame andbe secured thereto by means of the screw 16.'

t is preferred Ythat the usual trigger guard be removed to betterenable'the trigger operating means to be properly associated with thetrigger 17. Rigidly secured to the bottom walls are spaced.perpendicular blocks 18 that are positioned laterally of the trigger 1?`and are provided Awith clon` gated slots 19,'Athat are in horizontalalinement with tbe said trigger. Slidably mounted within the elongatedslots 19 is a soft iron armature 9.0 that is provided with rings 21suitable'for engaging the outer faces of the blocks 18 for retaining thearmature 2f) against longitudinal movement. Secured to the bottom 'wall4, and spaced forwardly from the armature 20 are perpendicular posts Q2having springs 23 secured thereto adjacent their upper ends andextending rearwardly to be secured to the armature Q0 as shown.
